Description
Electromagnetic Fields and WavesIntended for advanced undergraduate and graduate students, this well known and popular textbook provides an introduction to the physical principles, mathematical apparatus, and typical applications of classical electromagnetic theory. Beginning with the notion of scalar fields, Professor Rojansky leads the student through vectors and vector fields, the laws of Ohm, Joule, Coulomb, and Faraday, static electricity, and continues all the way to Maxwell's
Intended for advanced undergraduate and graduate students, this well-known and popular textbook provides an introduction to the physical principles, mathematical apparatus, and typical applications of classical electromagnetic theory. Beginning with the notion of scalar fields, Professor Rojansky leads the student through vectors and vector fields, the laws of Ohm, Joule, Coulomb, and Faraday, static electricity, and continues all the way to Maxwell's equations for bodies at rest, and to examples of electromagnetic waves. A particularly useful feature of the book is the author's introduction and explanation of the necessary mathematics as he goes along, rather than presuming student understanding. Although an extensive background is not necessary, a general knowledge of physics and calculus is a prerequisite.Throughout the book, the development of each topic is explicit and unhurried, an approach intended to avoid basic misconceptions that lead to major misunderstandings later on. Short exercises help the student test his grasp of the material, and the text is studded with diagrams and illustrations that supplement the content and elucidate many hard-to-visualize concepts. The book ends at a point where the use of Maxwell's equations in several important problems has been illustrated, and students are prepared to proceed to a variety of further topics.
Professor Rojansky brings many years of experience both as a teacher and a scientist (including ten years of advanced research at TRW Space Technologies Laboratories) to this lucid discussion of the fundamentals of electromagnetic fields and waves. His extensive pedagogical background enables him to communicate difficult concepts with great clarity.

Offers Complete Privacy
Color: Black, Size: 132in-Large Metal Base
We tried others that were nice but this particular room divider adds total privacy. We were looking for that. Easy to assemble. There is no gap if you position each petition close enough. The guality is very nice. Exactly what we were looking for.

Smooth, Stable, and Perfect for Flexible Spaces
Size: 88''W-4 Panel, Color: Grey, Size: 88''W-4 Panel, Color: Grey
This room divider is incredibly easy to move thanks to its industrial-grade silent casters. It glides smoothly across different floor types with just one hand and without any noise, while the built-in wheel locks keep it firmly in place once positioned, no slipping or unwanted movement.
The base with reinforced steel feet adds impressive stability, preventing wobbling even in busy or high-traffic areas. I also love the foldable design, which makes storage effortless when it’s not in use. It folds down compactly and fits neatly into small spaces.
I gave only 4 stars because I'm not crazy about the color of the fabric. Otherwise this is a very functional way to separate areas.

easy to put together, stable and blocks out unwanted eyes.
Size: 88''W-4 Panel, Color: Grey
If you live in a high rise building, or where there is lots of foot traffic and can see in your windows, this is a must have.
It's portable, can fold down one or two walls and easy to move around. Put together once, and block out light and eyes while tall enough to see over. You can fold it up along the wall, and use it to block out the blinds or light when using a projector so that it's darker.
You can use it to partician the room if you share one, and separate your pile of junk from your room so you don't look at it, can take quite a bit of towel weight and clothes and doesn't tip over.
Sturdy bottom metal and easy to put together.
I got the grey one, and glad I did. I use it everyday and is part of my room decor.
I love it, and after using it for a few months it's quite durable.
The quality is there for sure. A tad pricey, but worth it.
Must have for a private person.
